Hi guys, I know the Z3 wiring is a bit easier to work through on the front, but here it is if required. (One of these below is side different to the Haynes manual for wiring colour, either they mixed it up when printed or my car was stuffed up with the wrong wire installed in the wrong side of the harness. Have checked more than twice and I know I am not colour blind so who knows!) NEG = Brown for standard -ve wiring.
